2. Plywood is a smooth surface that offers the least friction.
3. The object resting over it will experience little or minimal friction as a result of this.

Explanation of the incorrect options

Option A: Sandpaper

1. Sandpaper is coarse, and rough surfaces have the greatest amount of friction.

Option B: Marble floor

1. Marble offers also friction.

Option C: Tree bark

1. Tree bark has more roughness on it, and offers more friction.

Therefore, the correct option is ( C ), Ply board.
